Khronos Releases OpenCL 1.1 Specification

Beaverton, Ore. – The Khronos Group today announced the ratification and public release of the OpenCL 1.1 specification, the latest version of the open, royalty-free standard for cross-platform, parallel programming of modern processors. OpenCL 1.1 provides enhanced performance and functionality for parallel programming in a backwards compatible specification that is the result of cooperation between industry-leading companies. OpenCL working group members include: AMD, Apple, ARM, Blizzard Activision, Broadcom, Codeplay, Electronic Arts, Ericsson, Freescale, Graphic Remedy, IBM, Imagination Technologies, Intel, Kestrel Institute, Los Alamos National Laboratory, Movidia, Nokia, NVIDIA, Petapath, Presagis, Qualcomm, Renesas, S3 Graphics, Seaweed Systems, Sony, ST-Ericsson, STMicroelectronics, Symbian, and Texas Instruments. Today Khronos also announced the release of a C++ wrapper API for use with OpenCL, and the immediate availability of OpenCL 1.1 conformance tests.
OpenCL 1.1 adds significant functionality for enhanced parallel programming flexibility, functionality and performance including:

• New data types including 3-component vectors and additional image formats;
• Handling commands from multiple hosts and processing buffers across multiple devices;
• Operations on regions of a buffer including read, write and copy of 1D, 2D or 3D rectangular regions;
• Enhanced use of events to drive and control command execution;
• Additional OpenCL C built-in functions such as integer clamp, shuffle and asynchronous strided copies;
• Improved OpenGL interoperability through efficient sharing of images and buffers by linking OpenCL and OpenGL events.

Khronos OpenCL Members Speak and Demo at SIGGRAPH Los Angeles July 27 to 29, 2010
Members of the press and developers alike are invited to attend the BOF “Birds of a Feather” on Tuesday, 27 July, 2010 from 4:00 pm - 6:00 pm at the SIGGRAPH trade show at Los Angeles Convention Center, Room 402A. There the audience will meet designers and implementers of this significant standard for heterogeneous parallel programming on GPUs and CPUs, and learn how OpenCL inter-operates with OpenGL, enabling advanced, cross-platform, visual computing applications. Guests are also invited to view demos on the Khronos booth #1201 and pickup a free laminated reference card for a number of our APIs, including OpenCL and OpenGL.
